Chrome: If you find yourself opening way too many tabs in Chrome and sucking up memory, TooManyTabs can suspend a few of them for awhile to make it run a little smoother, while keeping quick access to those tabs for later.

TooManyTabs has been around for Firefox for years, but if you're a Chrome user, there's also a Chrome version available—and it's a pretty good way to free up some of that memory that your tabs eat away. TooManyTabs gives you a simple dropdown menu from which you can see all the tabs you have open, and suspend them with the click of a button. By suspending tabs you want to keep open but don't need right this second, you can free up all that memory and still access them with one click later on.
